4 Claims. (Cl. 331-2) T his invention relates to improvements in a measuring devlce and more particularly to a dressmakers ruler and marking device.

The dressmakers ruler and marking device of the present invention is the result of a large amount of study and effort to provide a universal implement in but a single article.

The principal object of the present invention is, therefore, the provision of a dressmakers ruler and marking device that is versatile and extremely practical.

Another object of this invention is the provision of a dressmakers ruler and marking device that will accomplish the foregoing object and at the same time may be used for marking circles, arcs, and the like, within the limits of the implement.

A still further and specic object of the inventori is the provision of a dressmakers ruler and marking device that may be employed for marking straight lines in definite spaced relation to one another, marking spaces or areas in spaced relation to one another and, as noted above, used as a device for marking circles or arcs.

Other objects and advantages of the present invention should be readily apparent by reference to the following specication considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

Fig. 6 is a transverse sectional view similar to Fig. 5 taken through a plane to the right of said Fig. 5 on line 6--6 on Fig. 2.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

The dressmakers ruler and marking device of the present invention comprises a rectangular piece or sheet 10 of transparent material such as one of the synthetic resin materials particularly that known as a thermo plastic. Preferably the device of the present invention is formed of a sheet of material exactly fteen inches long and four (4) inches wide and of a thickness to prevent warping during and immedately after molding; it has been found that a thickness of approximately one-sixteenth GAG) of an inch answers the purpose intended.

Patented Sept. 15, 1959 ice The ruler 10 has its opposite edges 11 and 12 parallel throughout their length with the material immediately adjacent edge 11, for example, which may be termed the top, provided with inch and fractional inch markings 13 and suitably identified by numerals 14 as is customary with measuring rulers. The end edges 15 and 16 are parallel to one another and normal or at right angles to the edges 11 and 12.

The body of the ruler is provided with tive interrupted slots, 17, 18, 19, 20 and 21, Which are parallel with one another and is formed for the major length of the ruler. Each of said slots 17-21 is formed to a Width to receive the sharpened end of a pencil and a narrow tracing wheel so that the marking, or point of the marking, medium is substantially central of the slot when said pencil is held in a plane normal to the face of the ruler. Outwardly of each slot is a center line 22 extending substantially outwardly of the center of each slot.

The slots 1721 are spaced from one another diere-nt distances with said slot 17 spaced from the top edge 11 of the ruler a distance diiferent from the spacing of the slots 18, 19 and 20 with the slot 21 spaced from the bottom edge 12 of the ruler, again, a different distance from the spacing of the slots with respect to one another and the spacing of slot 17 from the top edge 11 of the ruler. If desired, and as illustrated in the drawings, two different slots may have the distance [between them equal to one another, if convenient, and if found in practice to be desirable. Accordingly, as illustrated in Figs. 1 and 2, the slot 17 is exactly one (l) inch from the top edge 11 with the slot 18 spaced from slot 17 and slot 19 spaced in from slot 18 one-half (1/2) of an inch on centers. The slot Ztl is spaced from slot 19 seven-eighths ('Ma) of an inch while slot 21 is spaced from slot Ztl three-fourths (3%1.) of an inch and -said slot 21 spaced three-eighths (SAS) of an inch from the lower or bottom edge 12 of the ruler. This combination of slot spacing permits lines to be drawn relative to one another and the edge of material at any desired distance or distances. lf it is desired to draw parallel lines having spaces greater than that accommodated by the several slots of the ruler Isaid spacing may be established by the standard inch and fractional inch markings at the top of the ruler.

As noted above each of the slots 17-21 is interrupted by a bridging web 23 with said web for each slot being in alignment with one another and located at approximately the midpoint of the length of the ruler thereby supplying said ruler with uniform thickness and a substantially uninterrupted cross section inwardly of each end of the ruler as well as at its midpoint. As will be seen from the `drawings the bridge 2.3 while of some length does not materially interfere with marking and does thereby add considerable rigidity to an otherwise highly iiexible device.

The portion of the ruler, indicated in the drawings by the reference numeral 24, located between slots 17 and 18, is provided with cross marks 25 each in line with the inch and fractional inch markings at the top edge of the ruler. These markings 25 are particularly advantageous in laying out button holes and the like at definite intervals and a definite distance from an edge of the material. In other words the edge of the material may be aligned with the top edge of the ruler and marking device, or the edge of said material may be aligned with the center line of one of the slots, which would put either slot 17 or slot 18 the desired distance from said material edge whereupon the button hole may be marked to the desired length as indicated by the markings 25 and with said button holes spaced from one another the desired distance which is again measured by the said mark ings 25. A relatively small hole or aperture 26 is formed through the portion 27 of the ruler lying between slots 18 and 19 and which may be employed in marking oi a circle `or are. `In other `words a blunt pencil or even the eraser .end of a pencil `may be inserted ,in .the ,11.919 or aperture 26 and act as a center or axis about which an arc is to be drawn and which arc will be marked with a second pencil, or `other marking medium, lQcated at the desired ruler marking 13 and `which marking medium will be caused to follow said ruler marking 4as the ruler itself is actuated about the axis ofthe hole or vaperture 2.5.

From the foregoing it .will be appreciated that there has been provided a dressmakers ruler and marking ,device which exible, transparent and of light weight, is `of an area that will hug the material on which it is deposited for the purpose of drawing lines on said material but which ruler and marking device can be readily Vmoved when necessary or desirable as in marking an arc or circle. The transparency of the ldevice `enables the user to readily see where the marks are to be made with nrespect to other marks, or the `design lof the material, or an edge, or other portion thereof. The ilexibility of the device permits'its use on folded material as well as over pins and the like and at the same time permits its marking edge to be adjacent the material during the marking thereof.
